Learn about the core concept and principles of Jimmutable Collection's framework in the Java class library

Jimmutable Collections: Core concept and principles in the framework in the Java class library Jimmutable Collections is a Java class library that provides a variable set framework to simplify and securely process data sharing in the multi -threaded environment.It is based on the concept of functional programming and emphasizes unsplis and thread security.In this article, we will introduce the core concepts and principles of Jimmutable Collections and provide some Java code examples. Core idea: 1. Immutability: The elements in the collection cannot be modified. Any modification operation will create a new collection object.This guarantees the security of data and simplifies shared data management in the multi -threaded environment. 2. Thread Safety: Jimmutable Collections is thread -safe. Multiple threads can access the collection objects at the same time and do not require additional synchronization mechanisms.Each thread can hold its own collection copy and modify and operate data independently. 3. Rich Functionality: Jimmutable Collection provides a series of functions, including insertion, deletion, searching, filtering, mapping, etc.These functions can easily process the collection data and maintain the unsophistication of the set. 4. Persistence: Any modification operation of the collection will generate a new collection object, and the original collection object will not be affected.This feature makes Jimmutable Collections have a long -lasting storage ability and can easily preserve the historical state of the collection. in principle: 1. Immutability First: Jimmutable Collections encourages the use of unsatisfactory objects to avoid direct modification operations in the collection.By creating a new collection object to represent the modified state, data competition and accidental modification are avoided. 2. Transparency: For the use of Jimmutable Collections, no need to care about the implementation details of the underlying collection.It provides a consistent interface and hides the complexity of the underlying implementation. 3. Composability: The function of Jimmutable Collection can be combined and nested with each other to form more complex operations.This combined characteristics make the code more concise and easy to understand. Example code: Below is a simple sample code using Jimmutable Collection: import org.organicdesign.fp.collections.FList; import org.organicdesign.fp.collections.FListIterator; public class JImmutableDemo { public static void main(String[] args) { // Create an unspeakable list FList<String> list = FList.of("apple", "banana", "orange"); // Add elements to the list and return a new list FList<String> updatedList = list.append("grape"); // Use the iterator to traverse the list FListIterator<String> iterator = updatedList.listIterator(); while (iterator.hasNext()) { System.out.println(iterator.next()); } } } In the above example, we created an unspeakable list, and used the `APPEND` method to add a new element to the list.Due to the unrelated characteristics, the `Append` method returns a new list containing new elements. When the iterator traverses the list, we can see all the elements in the list, including the "Grape" added before.This illustrates the thread security and unknown characteristics of Jimmutable Collections. Summarize: Jimmutable Collections is an unable variable collection framework for Java, which aims to process data sharing in a multi -threaded environment.It ensures the consistency of the data by non -variability and thread security, and provides rich functions to handle collection operations.The core principles of Jimmutable Collections are non -variable priority, transparency and combinedability.By following these principles, we can write more secure and reliable code and better process sharing data.
